2009 Ford Escape gauges drop to zero
Question:
I have a 2009 Ford Escape V6. The problem began while driving the gauges would all drop to zero briefly under a minute. When this happened nothing would change about speed or performance except the AC would stop blowing cold until the incident was over. This happened a few times here and there. Then the vehicle started cranking only sometimes. The only thing that seemed to help would be turning the steering wheel a little from the lock position. Then the issue progressed to the point of having issues getting it to crank at all.
Tapping on the dash seemed to help at some point. Had it checked by code reader that showed misfire over and over like 6 or 7 times. That mechanic suggested a wire short. Next mechanic suggested changing the ECM. Next mechanic to change the ignition switch. Next mechani to change the ignition module. Also something was draining the battery during this time. So I have changed the ignition switch, ignition module, replaced the battery, and last mechanic suggested cluster. Changed that too.
Am awaiting a mechanic to come by and flash the ECM. But not confident in his diagnosis either since he said that the cluster needs to be programmed to the vehicle. Pretty sure that’s not true. HELP! I don’t know what to do next.
Answer:
As for the claim that the cluster needs to be programmed to the vehicle, it's essential to verify this information with reliable sources, such as the vehicle's service manual or dealership technicians. Depending on the vehicle's make and model, the requirements for replacing and programming components can vary.
That being said here are some possibilities.
Gauges Dropping and AC Issues: The initial problem of the gauges dropping to zero and the AC stopping could indicate an electrical issue, possibly related to the instrument cluster or a loose connection.
Intermittent Cranking Issue: The intermittent cranking problem could be related to several factors, including the ignition system, starter motor, or even issues with the power supply to the starter.
Misfire Codes: The misfire codes could point to a problem with the ignition system, such as faulty spark plugs, ignition coils, or wiring issues.
Battery Drain: The battery drain is another significant issue that could be related to a parasitic draw caused by a faulty component or wiring.
ECM Reprogramming: It's not uncommon for ECM (Engine Control Module) reprogramming to be necessary after replacing certain components like the ignition switch or module. This helps ensure that the new components are properly integrated into the vehicle's system. However, reprogramming the ECM alone might not solve all the issues if there are underlying electrical problems.
Instrument Cluster Programming: While it's true that some vehicles require programming or calibration of the instrument cluster when replaced, it's not always the case for all models. In many instances, the replacement cluster should work plug-and-play without needing additional programming. However, it's worth verifying this with your vehicle's specific make and model.
Continued Troubleshooting: Since you've already replaced several components without fully resolving the issues, it might be necessary to continue troubleshooting. This could involve conducting a thorough inspection of the wiring harnesses, connectors, and grounds to identify any potential faults or shorts. A diagnostic scan tool capable of reading live data could also help pinpoint any ongoing issues with sensor readings or system voltages.
